Based on the data provided;
The formula for calculating density is given as:
From the formula above;
mass = density × volume
also, volume = area × height
Therefore,
mass = density × area × height
Calculating for the height of the liquid:
Height, L = 90.8 / (0.86 × 6.08)
L = 17.2 cm
The pressure due to a liquid is calculated using the formula below:
where;
h is height = 17.2 cm = 0.172 m
P is density = 0.86 g/cm^3 = 860 kg/m^3
g is acceleration due to gravity = 9.8 m/s^2
Pressure = 860 kg/m^3 × 0.172 m × 9.8 m/s^2
Pressure = 1449.616 N/m
